Use this procedure to move a vIST Controller node pair from one DvR domain to another.
For vIST to work properly, both Controller nodes must be in the same domain.
no router isis enable
no dvr controller
Caution
Disabling DvR on a DvR Controller destroys the domain ID and all dynamic content learned within the DvR domain. However, the switch retains the VLAN specific configuration which you can view using the command show running-config.
dvr controller <1–255>
router isis enable
Consider two vIST peer Controller nodes Switch1 (IP address 51.51.51.3) and Switch2 (51.51.51.4) that belong to a DvR domain (with domain ID 4), that you need to move to another domain (with domain ID 5).

Configure each node as a DvR Controller, with domain ID 5.
